TECHNICAL FIELD

The present disclosure relates to the field of control technology, and, in particular, to dual-mode voice control methods, devices, and user terminals.

BACKGROUND

With continuous popularization and development of mobile terminals, accessing the Internet with the mobile terminals has gradually become a trend. At present, many mobile terminals support a voice recognition function, which has been implemented mainly in the following two ways: (1) pressing a microphone button to start voice input, and releasing the microphone button to end voice input; and (2) using VAD (Voice Activity Detection) automatic recognition, and start voice input after entering a voice input interface.

The above two voice input recognition methods correspond to operation habits of different users and are applied to different scenarios respectively. The exiting various browsers and application software only support one of the implementation methods, and does not support mode selection and switching in the application scenarios where the voice input methods are both supported.

Some embodiments of the present disclosure provide a dual-mode voice control based on mobile application scenarios, which can better adapt to user behavior for voice input. Accordingly, users can speak directly and/or operate to input voice. By monitoring the behavior of the user and the state of the microphone, the two voice input modes can be individually selected and switched flexibly to provide a more convenient and reliable voice input service.

In some embodiments of the present disclosure, according to the voice input mode selected by a user, the voice mode mainly includes an operate-to-speak stop determination mode and a directly-speak automatic stop determination mode. The stop determination rule of the operate-to-speak stop determination mode is that a stop (e.g., a cease of input operation) is determined when an operation of ending the operate-to-speak stop determination mode (as opposed to an operation of activating the operate-to-speak stop determination mode) is detected. For example, the stop is determined when detecting that a finger or an electromagnetic pen releases a press-to-speak button, an uncheck-microphone button is clicked, the microphone button is slided to a starting point, and the like, regardless of whether the user carries out language description. Using the operation of pressing down the press-to-speak button to start a voice input and releasing the press-to-speak button to end the voice input as an example, in this operate-to-speak stop determination mode, as long as the user continues pressing down the speaking button, the voice mode is in the state of constantly acquiring voice information of the user, regardless whether the user carries out a voice input.

The stop determination rule of the directly-speak automatic stop determination mode is that a stop (e.g., cease of input operation) is determined if no voice input is detected for a certain time length, regardless of whether the user carries out an operation.

FIG. 2 shows a dual-mode voice control method, consistent with exemplary embodiments of the present disclosure. Referring to FIG. 2, a control method is disclosed. The method may direct to a browser in a user terminal or a voice function module such as an audio module in application software. The method includes the following steps.

Step S200 includes: determining whether a user has executed an operation of activating an operate-to-speak stop determination mode in a voice input interface.

A user in a search interface can select whether to enter a voice input interface. A simple way of entering the voice input interface can be defined, e.g., by the user clicking a “voice input” button on a screen interaction interface, performing a predefined gesture such as a gesture “V”, etc. Of course, directly entering the voice input interface can be the default. Described above is an example of entering the voice input interface, and it can be understood that the implementation of the preset disclosure is not limited thereto.

After entering the voice input interface, the user can directly speak to input voice or carry out an operation to input voice according to habits without selecting a voice input mode.

The operation of activating the operate-to-speak stop determination mode by the user refers to an operation directly triggering the operate-to-speak stop determination mode. There may be many operations of activating the operate-to-speak stop determination mode, and will be illustrated exemplarily in the following description.

Step S201 includes: in response to determining that the user has executed the operation of activating the operate-to-speak stop determination mode, determining whether a microphone is in a busy state, and if so, step S202 is executed: switching a voice mode from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode. Before the user executes the operation of activating the operate-to-speak stop determination mode, if the microphone is in the busy state, the voice mode is the directly-speak automatic stop determination mode. Otherwise, step S203 is executed: setting the operate-to-speak stop determination mode as the voice mode.

In some embodiments, the microphone in the busy state indicates a recording state in which the microphone receives user's voices, and correspondingly, the microphone in an idle state indicates a non-recording state when the microphone does not receive user's voices. In order to allow the user to conveniently recognizing the state of the microphone, a microphone recording icon appears in the middle of a screen to indicate the busy state, as shown in FIGS. 14, 15, 17, 19, 20, 22 and 23.

Whether the microphone is in the busy state can be determined in many methods. In one exemplary implementation, the user terminal includes a microphone state machine for acquiring the state of the microphone, the user terminal sends a microphone state acquisition instruction to the microphone state machine when determining that the user has executed the operation of activating the operate-to-speak stop determination mode, and the microphone state machine acquires the state of the microphone.

In some embodiments, when the microphone is in the busy state, the microphone is in a state of receiving and recording user's voice, and the voice mode is in a directly-speak automatic stop determination mode or an operate-to-speak stop determination mode. If it is determined that the user has executed the operation of activating the operate-to-speak stop determination mode when the microphone is in the busy state, it indicates that the voice mode was not in the operate-to-speak stop determination mode before the operation of activating the operate-to-speak stop determination mode is executed. Thus, when determining that the user has executed the operation of activating the operate-to-speak stop determination mode when the microphone is in the busy state, the current voice mode should be in the directly-speak automatic stop determination mode. When detecting that the user has executed the operation of activating the operate-to-speak stop determination mode in the directly-speak automatic stop determination mode, it can be determined that the user prepares for voice mode switching, and then the voice mode is switched from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode to implement mode switching, adapting to the voice input behavior of the user. Correspondingly, if the microphone is in an idle state when detecting that the user has executed the operation of activating the operate-to-speak stop determination mode in the directly-speak automatic stop determination mode, it directly enters the operate-to-speak stop determination mode.

Various methods may be used to determine whether the user has executed the operation of activating the operate-to-speak stop determination mode in the voice input interface. Two determination methods are provided below, and it can be understood that the implementation of the present disclosure is not limited thereto.

In the first determination method, as shown in FIG. 3, the monitoring whether a user has executed an operation of activating an operate-to-speak stop determination mode in a voice input interface of step 200 described above includes the following steps:

Step S300: determining whether the user has executed a start operation of activating an operate-to-speak stop determination mode in a voice input interface.

In some embodiments, the user executes the start operation of activating the operate-to-speak stop determination mode, for example, the start operation is a press-down operation to a press-to-speaker button, as shown in FIGS. 13 and 15; for another example, the start operation is a click operation to a microphone button, as shown in FIG. 16; for a further example, the start operation is a sliding operation from an initial position to a final position, e.g., sliding from left to right, etc.

The start operation of activating the operate-to-speak stop determination mode is implemented in various ways from the initial position to the final position, for example, the start operation is a gesture, e.g., the finger of the user slides from any position of the left side of the screen to any position of the right side of the screen, as shown in FIGS. 21 and 23. For another example, the screen has a microphone button and a sliding bar for sliding the microphone button, the start operation of activating the operate-to-speak stop determination mode is to drag the microphone button from one position to another in the sliding bar, as shown in FIGS. 18 and 20.

The microphone button may have multiple forms. For example, the microphone button may appear as a microphone button icon, e.g., a microphone icon is set in the middle of an area, and voice input can begin by long-pressing or selecting the microphone icon, as shown in FIGS. 16 and 17. For another example, the microphone button may appear as a long-press button, of which a press-to-speak label or the like is marked in a rectangular button, and voice input can begin by long-pressing the button, as shown in FIGS. 13 and 15.

During implementation, if the user selects an operate-to-speak voice input mode, the user may execute the start operation of activating the operate-to-speak stop determination mode; when the user executes the start operation of activating the operate-to-speak stop determination mode, the user terminal monitors the start operation of activating the operate-to-speak stop determination mode, e.g., clicking a microphone button, pressing down a long-press button, dragging the microphone button, sliding on the screen, etc., in which the finger of the user or the electromagnetic pen operated by the user touches the screen or the microphone button on the screen. Thus, the action behavior that the finger of the user or the electromagnetic pen operated by the user clicks the microphone button, presses down the long-press button, drags the microphone button or slides on the screen can be selected as the start operation to be monitored, or the contact action between the finger of the user or the electromagnetic pen operated by the user and the screen or the microphone button on the screen can be selected as the start operation to be monitored.

It can be known from the above description that the start operation of activating the operate-to-speak stop determination mode is used as a node for screening the user behavior in some embodiments.

Step S301 includes: if detecting the start operation, monitoring the time length during which the user executes the start operation, and when the time length reaches a preset threshold, determining that the operation of activating the operate-to-speak stop determination mode in the voice input interface is detected.

In some embodiments, detecting the start operation indicates the onset of the user's operation of activating the operate-to-speak stop determination mode. Taking the press-to-speak operation mode as an example, detecting the start operation in this step indicates the moment when the finger of the user presses down the microphone button, and the user did not operate the microphone button before the finger presses down the microphone button.

In view of possible mis-operations in practical applications, taking the example that the user long-presses the microphone button for voice input (as shown in FIG. 13) and releases the microphone button to end voice input (as shown in FIG. 14), the situation that the user transiently operates the microphone button exists in application. In such situation, if detecting that the user has executed the start operation of activating the operate-to-speak stop determination mode, e.g., when pressing down the microphone button, it is determined that the operation of activating the operate-to-speak stop determination mode in the voice input interface is detected, and that the operate-to-speak stop determination mode is set as the voice mode. Similarly, when the finger of the user releases the microphone button, it is determined to end the voice input according to the stop determination rule of the operate-to-speak stop determination mode. Such process may cause the problem that the information described by the user voice cannot be completely acquired.

Thus, to overcome the limitation in the prior art, in some embodiments, a mis-operation is determined by monitoring the time length that takes the user to execute the start operation, e.g., the time length during which the user presses down the microphone button. When the time length that takes the user to execute the start operation, e.g., the time length during which the user presses down the microphone button, is determined to reach a preset threshold, a correct operation can be determined. Then, the user can be determined to have executed the operation of activating the operate-to-speak stop determination mode in the voice input interface, and the state of the microphone is determined. If the microphone is in a busy state, the voice mode is switched from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode; and if the microphone is in an idle state, the operate-to-speak stop determination mode is set as the voice mode. On the other hand, if the time length that takes the user to execute the start operation does not reach the preset threshold, it is determined that the user has executed a mis-operation instead of the operation of activating the operate-to-speak stop determination mode in the voice input interface, and the voice mode is not switched.

In the second determination method, as shown in FIG. 4, the monitoring whether a user has executed an operation of activating an operate-to-speak stop determination mode in a voice input interface of step 200 described above includes the following steps:

Step S400: determining whether a user has executed a start operation of activating operate-to-speak stop determination mode in a voice input interface.

In this step, the user may execute the start operation similarly to that in step S300, which is not repeated here.

Step S401 includes: in response to determining that the user has executed the start operation of activating the operate-to-speak stop determination mode, determining whether the microphone is in an idle state. If yes, step S402 is executed: setting the directly-speak automatic stop determination mode as the voice mode; after which step S403 is executed: monitoring the time length that takes the user to execute the start operation; and when the time length reaches a preset threshold, determining that the operation of activating the operate-to-speak stop determination mode in the voice input interface is detected. Otherwise, step S404 is executed: when the time length of executing the start operation reaches the preset threshold, switching the voice mode from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode.

In this step, monitoring the start operation is the same as that in step S301, which is not repeated here.

The idle state of the microphone indicates a non-recording state when user's voice description is not received. In some embodiments, no microphone recording icon is in the screen when the microphone is in the idle state.

In some embodiments, if the microphone is in the idle state, the current voice mode is neither in the directly-speak automatic stop determination mode, nor in the operate-to-speak stop determination mode. Monitoring the start operation of activating the operate-to-speak stop determination mode in the idle state of the microphone indicates that the user prepares for voice input.

Based on the same consideration as in step S301, user's mis-operation may exist. Thus, in this step, when the user executing the start operation is detected, e.g., when the microphone button is pressed down and the microphone is in the idle state, the directly-speak automatic stop determination mode is set as the voice mode, and then the voice information described by the user is acquired in the directly-speak automatic stop determination mode, so that any interference caused by the mis-operation can be avoided, and the voice information described by the user can be completely acquired.

When the start operation is detected and the microphone is in the idle state, a mis-operation is determined by monitoring the time length that takes the user to execute the start operation, e.g., the time length that the user presses down the microphone button, while the directly-speak automatic stop determination mode is set as the voice mode. When the time length that takes the user to execute the start operation, e.g., the time length during which the user presses down the microphone button, is determined to reach a preset threshold, the operation can be determined not being a mis-operation. Then, it is determined that the user has executed the operation of activating the operate-to-speak stop determination mode in the voice input interface, and the state of the microphone is determined. If the microphone is in a busy state, the voice mode is switched from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode; and if the microphone is in an idle state, the operate-to-speak stop determination mode is set as the voice mode. On the other hand, if the time length that takes the user to execute the start operation does not reach the preset threshold, a mis-operation is determined, it is determined that the user executing the operation of activating the operate-to-speak stop determination mode in the voice input interface is not detected, and the voice mode is not switched.

The control method provided in this embodiment can be applied to various operation scenarios of starting the operate-to-speak stop determination mode. For example, if the start operation of activating the operate-to-speak stop determination mode is a press-down operation to the microphone button, the operation of activating the operate-to-speak stop determination mode is to press down the microphone button within a preset threshold, and the preset threshold is the time length of pressing down the microphone button. For another example, if the start operation of activating the operate-to-speak stop determination mode is a click operation to the microphone button, the operation of activating the operate-to-speak stop determination mode is to click the microphone button within a preset threshold, and the preset threshold is the time length of clicking the microphone button. For a further example, if the start operation of activating the operate-to-speak stop determination mode is a sliding operation to the microphone button from the left to the right side of the screen, the operation of activating the operate-to-speak stop determination mode is to keep the microphone button on the right side of the screen within a preset threshold, and the preset threshold is the time length of keeping the microphone button on the right side of the screen.

During implementation, the preset threshold can be set flexibly, the preset thresholds corresponding to different operations of starting the operate-to-speak stop determination mode may be different, e.g., the preset threshold of the time length of pressing down the microphone button may be 1 second; the preset threshold of the time length of clicking the microphone button may be 2 seconds; and the preset threshold of the time length of sliding the microphone button may be 3 seconds, etc.

In this embodiment, the start operation of ending the operate-to-speak stop determination mode is used as a node for screening the user behavior while the start operation of activating the operate-to-speak stop determination mode is used as another node for screening the user behavior.

As shown in FIG. 5, the method further includes the following steps.

Step S500 includes: acquiring voice information expressed by the user in the voice input interface.

When the user inputs voice in the voice input interface, the microphone is in a busy state, the voice mode is in an operate-to-speak stop determination mode or a directly-speak automatic stop determination mode, and the voice information expressed by the user in the operate-to-speak stop determination mode or the directly-speak automatic stop determination mode is acquired.

Step S501 includes: monitoring an operation of ending the operate-to-speak stop determination mode by the user in the voice input interface.

In some embodiments, according to different start operations executed by the user to start the operate-to-speak stop determination mode, the operation of ending the operate-to-speak stop determination mode can be implemented in various ways. For example, if the start operation is a press-down operation to a press-to-speak button, as shown in FIG. 13, the operate-to-speak voice input mode is to press down the press-to-speak button for voice input. Correspondingly, the operation of ending the operate-to-speak stop determination mode is to release the press-to-speak button, as shown in FIG. 14. For another example, if the start operation of activating the operate-to-speak stop determination mode is a click operation to the microphone button, as shown in FIG. 16, the operate-to-speak voice input mode is to click the microphone button for voice input. Correspondingly, the operation of ending the operate-to-speak stop determination mode is a click to cancel the selected microphone button, as shown in FIG. 17. For a further example, if the start operation of activating the operate-to-speak stop determination mode is to slide from an initial position to a final position, e.g., slide from left to right, the operate-to-speak voice input mode is to carry out voice input after sliding from left to right. Correspondingly, the operation of ending the operate-to-speak stop determination mode is to slide from the final position to the initial position, e.g., slide from right to left.

The start operation of activating the operate-to-speak stop determination mode is to slide from the initial position to the final position in multiple implementation modes, for example, the start operation is a gesture, e.g., the finger of the user or the electromagnetic pen operated by the user slides from any position on the left side of the screen to any position on the right side of the screen, as shown in FIG. 21. Correspondingly, the operation of ending the operate-to-speak stop determination mode is implemented when the finger of the user or the electromagnetic pen slides from any position of the right side of the screen to any position of the left side of the screen, as shown in FIG. 22. For another example, the screen has a microphone button and a sliding bar for sliding the microphone button, the start operation of activating the operate-to-speak stop determination mode is to drag the microphone button from one position in the sliding bar to the other position, as shown in FIG. 18. Correspondingly, the operation of ending the operate-to-speak stop determination mode is to drag the microphone button to the initial position, as shown in FIG. 19.

Step S502 includes: in response to detecting that the user has executed the operation of ending the operate-to-speak stop determination mode, determining whether the directly-speak automatic stop determination mode or the operate-to-speak stop determination mode is currently active. Step S503 includes: if the directly-speak automatic stop determination mode is currently active, continuing acquiring the voice information expressed by the user; and step S504 includes: if the operate-to-speak stop determination mode is currently active, stopping acquiring the voice information expressed by the user.

In some embodiments, FIGS. 15, 20, and 23 are schematic diagrams describing that the user executing the start operation of activating the operate-to-speak stop determination mode in the busy state of the microphone.

In some embodiments, when the user enters the voice input interface and before the voice input of the user is detected, the voice mode may not be set. That is, when the voice input of the user is not detected, the voice mode is neither in the directly-speak automatic stop determination mode nor the operate-to-speak stop determination mode. When user's voice is detected, the voice mode is set according to whether the user has executed the operation of activating the operate-to-speak stop determination mode. If voice is detected but the operation of activating the operate-to-speak stop determination mode is not detected, the directly-speak automatic stop determination mode is set as the voice mode; if voice is detected and the operation of activating the operate-to-speak stop determination mode is detected, the operate-to-speak stop determination mode is set as the voice mode.

In order to prevent mis-operation and ensure the integrity of the acquired voice information, in another mode, when user's voice is detected in the voice input interface, the directly-speak automatic stop determination mode is set as the voice mode regardless whether the user operates the microphone button. Thus, the device may also be defaulted during implementation, e.g., when the user enters the voice input interface, the directly-speak automatic stop determination mode is defaulted as the voice mode, then whether the user has executed the start operation of activating the operate-to-speak stop determination mode and the time length of executing the start operation are monitored, the voice mode is switched from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode when the time length reaches a preset threshold, otherwise, the directly-speak automatic stop determination mode continues.

In the dual-mode voice control method described above, the current voice input behavior of the user is accurately screened via two nodes, the two nodes are respectively the start operation of activating the operate-to-speak stop determination mode and ending the operate-to-speak stop determination mode. And the voice mode is automatically switched to the corresponding voice input support according to the state of the microphone and the voice input mode when different operations are detected, so that the voice input habits of different users are adapted, and the voice usage requirements of different behaviors can be met.

In the dual-mode voice control method provided in the first embodiment, when the start operation of activating the operate-to-speak stop determination mode is detected, the voice mode enters the directly-speak automatic stop determination mode, and when the time length of executing the start operation reaches the preset threshold, the voice mode is switched from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode, so that the integrity of acquired voice information is ensured and the effects of mis-operation are effectively avoided.

FIG. 6 shows a dual-mode voice control method provided by some embodiments of the present disclosure. As shown in FIG. 6, the control method flow may be implemented by a browser in a user terminal or a voice function module such as an audio module in application software, and the method includes the following steps:

Step S600 includes: monitoring whether a user has executed a start operation of activating an operate-to-speak stop determination mode in a voice input interface.

In some embodiments, the user may execute the start operation of activating the operate-to-speak stop determination mode in multiple implementations. For example, the start operation is a press-down operation to a press-to-speaker button, as shown in FIG. 13. For another example, the start operation is a click operation to a microphone button, as shown in FIG. 16. For a further example, the start operation is a sliding operation from an initial position to a final position, e.g., sliding from left to right, etc.

The microphone button is shown in multiple forms, for example, shown as a microphone button icon, e.g., a microphone icon is set in the middle of an area, and voice input can begin by long-pressing or selecting the microphone icon, as shown in FIGS. 16 and 17; for another example, shown as a long-press button, of which a press-to-speak label or the like is marked in a rectangular button, and voice input can begin by long-pressing the button, as shown in FIGS. 13 and 15.

It can be known from the above description that the start operation of activating the operate-to-speak stop determination mode can be used as a node for screening the user behavior.

Step S601 includes: in response to detecting the start operation, determining whether the microphone is in an idle state; if yes, step S602 is executed: setting the directly-speak automatic stop determination mode as the voice mode; step S603 includes: monitoring the time length that takes the user to execute the start operation; and step 604 includes: when the time length reaches a preset threshold, determining that the operation of activating the operate-to-speak stop determination mode in the voice input interface is detected, and switching the voice mode from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode. If the response to step S601 is no, step S605 is executed: when the time length of executing the start operation reaches the preset threshold, switching the voice mode from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode.

Detecting the start operation indicates the moment when the user's operation of activating the operate-to-speak stop determination mode appears. Taking the press-to-speak operation mode as an example, detecting the start operation in this step indicates the moment when the finger of the user presses down the microphone button, and the user did not operate the microphone button before the moment when the finger of the user pressed down the microphone button.

The idle state of the microphone indicates a non-recording state when no voice description is received. In some embodiments, no microphone recording icon is in the screen in the idle state of the microphone.

In some embodiments, if the microphone is in the idle state, the current voice mode is neither the directly-speak automatic stop determination mode nor the operate-to-speak stop determination mode. Monitoring the start operation of activating the operate-to-speak stop determination mode in the idle state indicates that the user prepares for voice input.

Since user's mis-operation may exist, in this step, when the start operation is detected, e.g., when the microphone button is pressed down and the microphone is in the idle state, the directly-speak automatic stop determination mode is set as the voice mode, and then the voice information described by the user is acquired in the directly-speak automatic stop determination mode, so that interferences caused by the mis-operation can be avoided, and the voice information can be completely acquired.

When the start operation is detected and the microphone is in the idle state, a mis-operation is determined by monitoring the time length during which the user executes the start operation, e.g., the time length during which the user presses down the microphone button, while the directly-speak automatic stop determination mode is set as the voice mode. When the time length during which the user executes the start operation, e.g., the time length during which the user presses down the microphone button, is determined to reach a preset threshold, a correct operation can be determined, then it is determined that the user has executed the operation of activating the operate-to-speak stop determination mode in the voice input interface, and the voice mode is switched from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode. On the other hand, if the time length during which the user executes the start operation does not reach the preset threshold, a mis-operation is determined, it is determined that the user has not executed the operation of activating the operate-to-speak stop determination mode in the voice input interface, and the voice mode is not switched.

In some embodiments, the user's operation of ending the operate-to-speak stop determination mode is used as the other node for screening the user behavior.

The method further includes: acquiring voice information expressed by the user in the voice input interface; monitoring an operation of ending the operate-to-speak stop determination mode by the user in the voice input interface; when detecting that the user executes the operation of ending the operate-to-speak stop determination mode, determining whether the directly-speak automatic stop determination mode or the operate-to-speak stop determination mode is currently active; if the directly-speak automatic stop determination mode is currently active, continuing acquiring the voice information expressed by the user; and if the operate-to-speak stop determination mode is currently active, stopping acquiring the voice information expressed by the user, as shown in FIG. 5.

In some embodiments, according to different start operations, executed by the user, of activating the operate-to-speak stop determination mode, the operation of ending the operate-to-speak stop determination mode is implemented in various ways. For example, if the start operation is a press-down operation to a press-to-speak button, as shown in FIG. 13, the operate-to-speak voice input mode is to press down the press-to-speak button for voice input. Correspondingly, the operation of ending the operate-to-speak stop determination mode is to release the press-to-speak button, as shown in FIG. 14. For another example, if the start operation of activating the operate-to-speak stop determination mode is a click operation to the microphone button, as shown in FIG. 16, the operate-to-speak voice input mode is to click the microphone button for voice input. Correspondingly, the operation of ending the operate-to-speak stop determination mode is a click operation to cancel the selected microphone button, as shown in FIG. 17. For a further example, if the start operation of activating the operate-to-speak stop determination mode is to slide from an initial position to a final position, e.g., slide from left to right, the operate-to-speak voice input mode is to carry out voice input after sliding from left to right. Correspondingly, the operation of ending the operate-to-speak stop determination mode is to slide from the final position to the initial position, e.g., slide from right to left.

The start operation of activating the operate-to-speak stop determination mode by sliding from the initial position to the final position has multiple implementation modes. For example, the start operation is a gesture action, e.g., the finger of the user or the electromagnetic pen operated by the user slides from any position of the left side of the screen to any position of the right side of the screen, as shown in FIG. 21, and correspondingly, the operation of ending the operate-to-speak stop determination mode is implemented when the finger of the user or the electromagnetic pen slides from any position of the right side of the screen to any position of the left side of the screen, as shown in FIG. 22. For another example, the screen has a microphone button and a sliding bar for sliding the microphone button, the start operation of activating the operate-to-speak stop determination mode is to drag the microphone button from one position in the sliding bar to the other position, as shown in FIG. 18. Correspondingly, the operation of ending the operate-to-speak stop determination mode is to drag the microphone button to the initial position, as shown in FIG. 19.

In some embodiments, the stop determination rule of the operate-to-speak stop determination mode is that stop is determined when an operation of ending the operate-to-speak stop determination mode as opposed to an operation of activating the operate-to-speak stop determination mode is detected, e.g., stop is determined when operations as a finger or an electromagnetic pen releasing a press-to-speak button, an uncheck-microphone button being clicked, the microphone button being slided to a starting point and the like are monitored, regardless of whether the user inputs a voice description. Using the operation of pressing down the press-to-speak button to input voice and releasing the press-to-speak button to end voice input as an example, in this operate-to-speak stop determination mode, as long as the user presses down the speaking button, the voice mode is in the state of acquiring voice information described by the user any time regardless whether the user inputs a voice.

The stop determination rule of the directly-speak automatic stop determination mode is that stop is determined if voice information described by the user is not detected for a certain time length, regardless of whether the user carries out an operation.

In the dual-mode voice control method described above, when the user executing the start operation of activating the operate-to-speak stop determination mode is detected, the voice mode enters the directly-speak automatic stop determination mode, and when the time length of executing the start operation reaches the preset threshold, the voice mode is switched from the directly-speak automatic stop determination mode to the operate-to-speak stop determination mode, so that the integrity of acquired voice information is ensured and the effect of mis-operations is effectively avoided.

In some embodiments, for the methods of entering the voice input interface, triggering the operate-to-speak stop determination mode, executing the start operation, setting and switching the voice mode and the like, reference may be made to the descriptions in the first embodiment, which are not repeated here.
